The invention provides a rotary ball core dirt removing mechanism. The mechanism is installed in a valve body and comprises a ball core; a first scraping plate and a second scraping plate are arrangedin the valve body; in the opening and closing processes of the ball core, the first scraping plate scrapes off a crystallization medium on the inner wall of the valve body, and the second scraping plate scrapes off a crystallization medium on the surface of the ball core. In the opening and closing processes of the ball core, the first scraping plate and the second scraping plate automatically remove crystallization media on the surface of the ball core and the inner wall of the valve body, so that the sealing surface of a sealing piece is protected, the ball core is prevented from being jammed or locked, shutdown and output reduction are avoided, and long-period normal operation is achieved. 本发明提供一种旋转式球芯除垢机构，安装于阀体内，包括球芯，所述阀体内设有第一刮板和第二刮板，所述球芯启闭过程中，所述第一刮板刮除所述阀体内壁的结晶介质，所述第二刮板刮除所述球芯表面的结晶介质。第一刮板和第二刮板在球芯的起闭过程中，自动清除球芯表
